V`When it' is ydesired Vto lock thel wheels 4to the aXleto lift the plowfroni the position shown in Figure 2, thisis acoon'r V p'lished'by 'rocking forwardlyVK a leverV '63,

which is pivotally mounted at 64 upon the bearing 20, which is secured to the body supporting frame, as above described. its the r'leveriis swungabout its pivot, a lip 653 formed on the depending` arin 66 of the lever engages an arin 67 Vsecured to the transverse shaft andv rocks the shaft against the tension of the spring the cranks thereof ac-` tuating the linksV 544-55 which swing1 the dogs 56-58 about their 'pivots 57-59 and into they pathv of the teeth as best seen in Figure 4.

As the plowr is drawn forwardly and appreaches itsl point of highest elevation by being rocked over the locked axle system, o.

Ef it is desired to vary the plowing,` depth the lever 78 isshifted to adjust the stop 8l to obtain the desired result, it beine` understood that if the lever is raised tocar! ry the stop higher in the slotj the suck of the plows will cause -theni to penetrate deep er' andthe axle will swing' downward further before the Astop is engaged by the bottom of the slot in the link S3, ..vhileif the A115 lever is lowered the stop 8l will be engaged `by such shoulderwhenthe crank axle has been swung vdownward.
